### ⭐⭐⭐⭐ 







  
  
    keep spares of these valves on hand to ensure a/c equipment does not detect a false vehicle leak
  

*by P***C on Reviewed in Canada on 28 December 2016*

I purchased this item and its companion low-pressure (blue knob) service valve independently since the combined set was overpriced compared to previous same-purchase last year.  Waited  for sale on these individual high/low valves so that 2 individual purchased combined matched pricing on set from previous purchase.  The valves seem solid and have proved to be durable;  but due to the nature of these valves they are not guaranteed to remain leak-free indefinitely.  For this reason we keep ample supply of valves on-hand to prevent a/c equipment from otherwise falsely flagging an a/c leak on a vehicle.  The delivery time was as expected but would have preferred not to have waited so long for price to drop to reasonable levels, so deduct one star only.  There are cheaper choices out there, but a/c machines are very sensitive to leaks when hooked up to the vehicle; so minimize the risk of a false flag and get quality Robinair valves and replaced whenever needed.

    Low side coupler leaks badly
  

*by W***L on Reviewed in Canada on 9 September 2020*

I bought Robinair thinking it would be a reputable manufacturer, but I should have read the reviews, as the low side coupler leaks badly, like many people's review on this item.
